Republicans have made Reid a top target for defeat this fall, as high jobless numbers and a slower recovery plague Nevada's economy. Reid has suffered from low approval ratings over the past year, suggesting that he was low-hanging fruit for a GOP challenger this fall.

But Reid's been making up ground recently against Angle, whose candidacy had been fueled by conservative activists and some within the Tea Party movement. Her conservative support led her to upset former state GOP Chairwoman Sue Lowden in the party's primary to face Reid.

Reid noted his tough approval ratings, but said that he'd campaigned through negative seasons before and that Nevada voters were familiar with his record by this point.

"I have a campaign that’s moving along just fine," he said. "I feel comfortable where we are today."
